Abstract: A system for positioning an engine control element has a sensor measuring a value corresponding to the actual position of the element, a reference providing a command value establishing the proper position for the element, an electronic control which compares the measured value with the command value, and an actuator including a fluid pressure responsive motor for moving the element and a pressure regulator directed by the electronic control to regulate the fluid pressure delivered to the motor and cause the motor to move the control element to the proper position. The pressure regulator has a coil energized by the electronic control and a valve member which floats between a regulated-pressure-reducing bias caused by the magnetic flux created in the coil and a regulated-pressure-increasing bias caused by a varying but uncontrolled pressure differential.
